It is bad to live for necessity; but there is no necessity to
live in necessity.
[Lat., Malum est necessitati vivere; sed in necessitate vivere
necessitas nulla est.]
- Seneca (Lucius Annaeus Seneca), Epistles
(58)

What fate imposes, men must needs abide; it boots not to resist
both wind and tide.
- William Shakespeare

Now we sit close about this taper here
And call in question our necessities.
- William Shakespeare, Julius Caesar
(Brutus at IV, iii)

No, rather I abjure all roofs, and choose
To wage against the emnity o' th' air,
To be a comrade with the wolf and owl,
Necessity's sharp pinch.
- William Shakespeare, King Lear
(King Lear at II, iv)

Omission to do what is necessary
Seals a commission to a blank of danger;
And danger, like an ague, subtly taints
Even then when we sit idly in the sun.
- William Shakespeare, The History of Troilus and Cressida
(Patroclus at III, iii)

Teach thy necessity to reason thus:
There is no virtue like necessity.
- William Shakespeare, The Tragedy of King Richard the Second
(Gaunt at I, iii)
